Sensor and actuator electronic system for active hand pose sensing

We designed, developed and validated a bone conduction-based hand pose sensing wireless and wearable system, capable of distinguishing different hand gestures and enabling the evaluation of the pose angles of the fingers. The system can be used as a valuable alternative to sensory gloves, image processing or electromyographic signal analysis. BCHS has the advantage of significantly reducing the size of the recognition system, not requiring a confined environment as with camera systems, having no blind spots, and being minimally invasive to the user. The test results demonstrated the feasibility of the proposed measurement techniques and encourage further activities for the development of a complete system by embedding the post-processing tasks into the wearable device.
